' To all whom it may ooncem:

Be it known that I, CLARENCE F. ColvAn'r,

a citizen of the United States,-residing at Portland, in the county of Multnomah, State of Oregon, haveinvented certain new and useful Improvements in \Vindow- Cleaners; and I do herebyde'clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to window wipers and has for an object to provide a window wiper that may be easily and quickly attached to or removed from a vestibule win,-

spring for normally holding the wiper out of engagement with the window and for forming a cushion to prevent the wiper" position upon a vestibule window. Fig. 2

is a vertical sectional view through the window wlth the device shown 1n elevatlon and in normal position. Fig. 3 is a longi-- tudinal sectional view through the window and through the 'device :with the latter shown in active position. Fig. 4 is a detail perspective View of the wiper holder. Fig.

5 is a detail perspective view of the inner: F1g. 6 1s a vertical se'ctlonal view taken on the line 66 Fig. 2. Referring now to the drawing in which like characters of reference designate simi-- lar parts, 10 designates a vestibule window and 11 the window casing thereof. In the present embodiment of my invention I employ a tube 12 which is engaged through the window casing above the window and is equipped near the outer end with a circumferential fiange'13 which is secured to the outside of the casing by screws 14 or similar connectors. The tube is provided inof a set screw 27.

ternally substantially midway bet-ween the ends with stop lugs 15.

An inner tube 16 is slidably fitted and also revolubly fitted within the tube 12, and is of greater-length than the latter. The

inner tube is provided with longitudinal slots l7,as most clearly shown in Fig. 5,

these slots receiving the stop lugs 15. 'A

helical spring 18 encircles the inner tube and is confined between the stop lugs 15 and a terminal flange 19 projecting form the outer end of the inner tube. This flange normally holds the inner tube at its outer limit of movement in the outer tube 12 and also performs thefunction ofa cushion to minimize shocks and jars. as the inner tube is'drawn rear'w'ardly through the outer tube.

The wiper comprises a substantially V- shaped rod-20 one legof'which projects entirely through the inner tubeand is equipped terminally with an ,L-shaped grip 21, connection" between the leg and grip being made by a spring pressed pivoted pawl" 22 having a terminal lug 23 which 'projects into a notch 2- 1 formed in the leg as shown in F ig. 3. The other leg of the rod is formed at the end with acounterbore 25 into which the reduced end of the wiper handle 26 is adjustably secured by-means The wiper handle is terminally equipped with curvilinear spring plates 28 which are adapted to embrace a rubber wiper 29.

To operate the device it :is simply necessary to pull rearwardly upon the grip 21, the rod 19 being thereby carried bodily through the outer tube and carrying the'inner tube along with it, while the wiper is carried into engagement "with the window,

pane. The grip may now be twisted to rotate the rod 19'and swing the wiper in an are upon the window pane as shown by dotted lines in Fig. 1. From the above description it will be seen that the helical spring 18 performs the dual function of holding the wiper out of engagement with the window pane and also forming a cushion which prevents the Wiper from coming into sharp contactv with and breaking the window pane.

For preventing snow ing above the arm 20 and impeding the proper working of thelatter, I provide a shield 30 which overhangs the arm 20 and and ice accumulatire provided with e termina. 60113.1 that is fixedly secured to tube l2; s

What iselaimed, is:

5 A window wiper including an outer tube having internal stop lugs, 'an inneritube slidably and revolubly fitte in said outer the 'oute 1 end of -the tube and having oppositely isposed 1ongi- 'tudmal islets receiving said stop lugs, 21.

'lq'flange 0n the outer end of said inner tube, a hehcal spring on said inner tube confined between-said flangeand saidstop lugs-and 7 normally ho1ding--said inner tubeat the N- outer limit of its movement, a substantially V-shaped rod. having one 1eg-'pro ecting 15 through said inner tube and terminally equipped with a removable grip, and a. Wiper on the other leg of -said rod. In testimony whereof, Iaflix my signature,.in presence of two witnesses? CLARENCE FRANKLIN C0NANT H Witnesses: NEIL SMITH, 1 W. G. DEATSMAN.
